If you’re using SEM as a strategy, you’ll need to test and evaluate your keywords. A good rule of thumb is that for every 100 clicks you get, you’ll get between 3 and 10 enquiries. So, to conduct an efficient test, you’ll want to test around 1,000 clicks. That means setting your budget for Adwords at 1,000 times the cost of the click. If you find that this is going to cost too much, you’ll need to find other keywords or a different marketing strategy.
White balance tells your camera the color temperature of the environment you’re shooting in. Different types of light have different colors. For example, incandescent bulbs (like what many people put in a lamp) have a very warm color. The florescent lights (if you’re reading this in an office, look up) are a little bit cooler. Daylight is cooler yet. Before you begin shooting, you have to adjust your camera’s white balance according to your setup.
SEO techniques can be classified into two broad categories: techniques that search engine companies recommend as part of good design ("white hat"), and those techniques of which search engines do not approve ("black hat"). The search engines attempt to minimize the effect of the latter, among them spamdexing. Industry commentators have classified these methods, and the practitioners who employ them, as either white hat SEO, or black hat SEO. White hats tend to produce results that last a long time, whereas black hats anticipate that their sites may eventually be banned either temporarily or permanently once the search engines discover what they are doing.
